Ivan IV Vasilyevich, crowned the first Tsar of All Russia in 1547, remains one of history’s most divisive figures. Was he a paranoid monster who terrorized his own people, or a visionary who forged a unified Russian state from feudal chaos? This show, hosted by Lucas and Luna, dissects Ivan’s reign from his childhood as a neglected grand prince to his death in 1584, leaving a wrecked but centralized realm. We examine the ‘Glorious Years’ of reform: his creation of a new legal code (Sudebnik of 1550), the formation of the streltsy (first standing army), and the convocation of the Zemsky Sobor. We explore the conquest of the Khanates of Kazan (1552) and Astrakhan (1556), which opened the Volga River and transformed Russia into a multi-ethnic empire. But then comes the pivot: the devastating Livonian War (1558–1583), a 25-year conflict that bled Russia dry for a Baltic foothold. We trace Ivan’s psychological unraveling after the death of his wife Anastasia, his creation of the Oprichnina—a shadow state of 6,000 black-clad henchmen who terrorized the boyars and massacred cities like Novgorod (1570). We weigh the evidence: was the Oprichnina a calculated tool to break aristocratic resistance, or the product of paranoia? We discuss Ivan’s cultural legacy—the introduction of printing, the construction of St. Basil’s Cathedral (a monument to Kazan’s fall), and his intellectual correspondence with defector Prince Kurbsky. And we confront the ultimate mystery: why did he kill his own son and heir, Ivan Ivanovich, in 1580? Join us as we navigate the contradictions of a tsar who built a nation and destroyed a family.
